在连续连接介质模型和修正比拟桁架模型基础上,通过理论分析分别推导了计入剪切变形的延性联肢墙屈服位移和极限位移的算式,首次建立起考虑剪切变形的延性联肢墙位移曲率延性关系,并通过与13片联肢墙试验结果的对比研究验证了该延性关系的准确性。研究结果表明,考虑剪切变形的延性联肢墙位移延性系数离散程度较小、均匀性较好,建立的延性关系可应用于联肢剪力墙结构的能力设计。
Based on the continuous connection of the medium model and the modified truss model, the formulas of the yield displacement and the limit displacement of the ductile joint wall which are included in the shear deformation are deduced respectively by theoretical analysis. For the first time, the displacement of ductile associated wall considering the shear deformation is established The relationship between the ductility and the ductility was verified by comparison with the experimental results of thirteen joint walls. The results show that the displacement ductility coefficient of the ductile joint wall considering shear deformation is small and the uniformity is good. The established ductility relation can be applied to the capacity design of the joint-type shear wall structure.
